Introduction
Many edible backyard weeds have dangerous doppelgängers that look harmless but can cause poisoning, neurological damage, or organ failure if consumed. Foraging accidents almost always occur due to misidentification.
“The most common cause of plant-related poisoning is confusion between edible species and visually similar toxic plants.” — American Association of Poison Control Centers
